From 81cc3f868d30884c6f2d2bf5d1861fbeb24ddebd Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Tue, 25 Nov 2014 18:17:34 +0000 Subject: ARM: vexpress: Remove non-DT code Now, with the CLCD DT support available, there is no more reason to keep the non-DT support for V2P-CA9. Removed, together with "some" supporting code. It was necessary to make PLAT_VERSATILE_SCHED_CLOCK optional and selected by the machines still interested in it.
